Do you have an issue with a specific file(s)?
No

Can you reproduce using one of our samples or online demos?
Yes

Are you using the WebViewer server?
Yes, but it is not relevant as far as i can tell.

Does the issue only happen on certain browsers?
No

Is your issue related to a front-end framework?
I’m using Angular, but it also happens with the normal WebViewer-Demo, so i think it is not angular specific.

Is your issue related to annotations?
No

Please give a brief summary of your issue:
Open the WebViewer-Demo (PDFTron WebViewer Demo: JavaScript PDF Viewer Demo). Open Developer Tools and change to mobile view. An error occurs, that the PDF can’t be loaded:

Hello Christian,

Thank you for contacting WebViewer Support.

​Unfortunately, I was not able to reproduce the error. Here are the steps I took with video link:

  2. Open Chrome Dev Tools
  3. Open toggle device toolbar and set to sample mobile devices, no error pops up

Hello Kevin,

with JavaScript PDF Viewer Demo i can’t reproduce the error, but with PDFTron WebViewer Demo: JavaScript PDF Viewer Demo the error occurs.

In Safari it seems to work, but Edge, Chrome and Vivaldi gave me the error.

Steps:

  1. Open PDFTron WebViewer Demo: JavaScript PDF Viewer Demo
  2. Open Dev Tools
  3. Open toggle device toolbar and set for example iPhone SE
  4. Reload the Page, only then the error appears.

Best Regards
Christian

Hello Kevin,

thank you. As long as it works on Android and iOS mobile this is not really important. For test purposes it is sometimes nice to change the layout within the browser.
But for now it is ok to know, that it will be fixed in the future.
